* RDMA/core: Add iWARP protocol statistics attributes in sysfsSteve Wise2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a sysfs attribute group called "proto_stats" under /sys/class/infiniband/$device/ and populates this group with protocol statistics if they exist for a given device. Currently, only iWARP stats are defined, but the code is designed to allow InfiniBand protocol stats if they become available. These stats are per-device and more importantly -not- per port. Details: - Add union rdma_protocol_stats in ib_verbs.h. This union allows defining transport-specific stats. Currently only iwarp stats are defined. - Add struct iw_protocol_stats to define the current set of iwarp protocol stats. - Add new ib_device method called get_proto_stats() to return protocol statistics. - Add logic in core/sysfs.c to create iwarp protocol stats attributes if the device is an RNIC and has a get_proto_stats() method.

* IPoIB/cm: Fix racy use of receive WR/SGL in ipoib_cm_post_receive_nonsrq()Roland Dreier2008-07-15
| | | | | | | | | | | | | | | | | | | | For devices that don't support SRQs, ipoib_cm_post_receive_nonsrq() is called from both ipoib_cm_handle_rx_wc() and ipoib_cm_nonsrq_init_rx(), and these two callers are not synchronized against each other. However, ipoib_cm_post_receive_nonsrq() always reuses the same receive work request and scatter list structures, so multiple callers can end up stepping on each other, which leads to posting garbled work requests. Fix this by having the caller pass in the ib_recv_wr and ib_sge structures to use, and allocating new local structures in ipoib_cm_nonsrq_init_rx(). Based on a patch by Pradeep Satyanarayana <pradeep@us.ibm.com> and David Wilder <dwilder@us.ibm.com>, with debugging help from Hoang-Nam Nguyen <hnguyen@de.ibm.com>.

* IB/core: Reset to error QP state transition is not allowedRalph Campbell2008-07-15
| | | | | | | | | | | | | | | I was reviewing the QP state transition diagram in the IB 1.2.1 spec and the code for qp_state_table[], and noticed that the code allows a QP to be modified from IB_QPS_RESET to IB_QPS_ERR whereas the notes for figure 124 (pg 457) specifically says that this transition isn't allowed. This is a clarification from earlier versions of the IB spec, which were ambiguous in this area and suggested that the RESET to ERR transition was allowed. Fix up the qp_state_table[] to make RESET->ERR not allowed. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB/mlx4: Configure QPs' max message size based on real device capabilityEli Cohen2008-07-15
| | | | | | | | | | | | ConnectX returns the max message size it supports through the QUERY_DEV_CAP firmware command. When modifying a QP to RTR, the max message size for the QP must be specified. This value must not exceed the value declared through QUERY_DEV_CAP. The current code ignores the max allowed size and unconditionally sets the value to 2^31. This patch sets all QPs to the max value allowed as returned from firmware. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* RDMA/core: Add memory management extensions supportSteve Wise2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the IB "base memory management extension" (BMME) and the equivalent iWARP operations (which the iWARP verbs mandates all devices must implement). The new operations are: - Allocate an ib_mr for use in fast register work requests. - Allocate/free a physical buffer lists for use in fast register work requests. This allows device drivers to allocate this memory as needed for use in posting send requests (eg via dma_alloc_coherent). - New send queue work requests: * send with remote invalidate * fast register memory region * local invalidate memory region * RDMA read with invalidate local memory region (iWARP only) Consumer interface details: - A new device capability flag IB_DEVICE_MEM_MGT_EXTENSIONS is added to indicate device support for these features. - New send work request opcodes IB_WR_FAST_REG_MR, IB_WR_LOCAL_INV, IB_WR_RDMA_READ_WITH_INV are added. - A new consumer API function, ib_alloc_mr() is added to allocate fast register memory regions. - New consumer API functions, ib_alloc_fast_reg_page_list() and ib_free_fast_reg_page_list() are added to allocate and free device-specific memory for fast registration page lists. - A new consumer API function, ib_update_fast_reg_key(), is added to allow the key portion of the R_Key and L_Key of a fast registration MR to be updated. Consumers call this if desired before posting a IB_WR_FAST_REG_MR work request. Consumers can use this as follows: - MR is allocated with ib_alloc_mr(). - Page list memory is allocated with ib_alloc_fast_reg_page_list(). - MR R_Key/L_Key "key" field is updated with ib_update_fast_reg_key(). - MR made VALID and bound to a specific page list via ib_post_send(IB_WR_FAST_REG_MR) - MR made INVALID via ib_post_send(IB_WR_LOCAL_INV), ib_post_send(IB_WR_RDMA_READ_WITH_INV) or an incoming send with invalidate operation. - MR is deallocated with ib_dereg_mr() - page lists dealloced via ib_free_fast_reg_page_list(). Applications can allocate a fast register MR once, and then can repeatedly bind the MR to different physical block lists (PBLs) via posting work requests to a send queue (SQ). For each outstanding MR-to-PBL binding in the SQ pipe, a fast_reg_page_list needs to be allocated (the fast_reg_page_list is owned by the low-level driver from the consumer posting a work request until the request completes). Thus pipelining can be achieved while still allowing device-specific page_list processing. The 32-bit fast register memory key/STag is composed of a 24-bit index and an 8-bit key. The application can change the key each time it fast registers thus allowing more control over the peer's use of the key/STag (ie it can effectively be changed each time the rkey is rebound to a page list).

* IPoIB: Copy small received SKBs in connected modeEli Cohen2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The connected mode implementation in the IPoIB driver has a large overhead in the way SKBs are handled in the receive flow. It usually allocates an SKB with as big as was used in the currently received SKB and moves unused fragments from the old SKB to the new one. This involves a loop on all the remaining fragments and incurs overhead on the CPU. This patch, for small SKBs, allocates an SKB just large enough to contain the received data and copies to it the data from the received SKB. The newly allocated SKB is passed to the stack and the old SKB is reposted. When running netperf, UDP small messages, without this pach I get: UDP UNIDIRECTIONAL SEND TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 14.4.3.178 (14.4.3.178) port 0 AF_INET Socket Message Elapsed Messages Size Size Time Okay Errors Throughput bytes bytes secs # # 10^6bits/sec 114688 128 10.00 5142034 0 526.31 114688 10.00 1130489 115.71 With this patch I get both send and receive at ~315 mbps. The reason that send performance actually slows down is as follows: When using this patch, the overhead of the CPU for handling RX packets is dramatically reduced. As a result, we do not experience RNR NAK messages from the receiver which cause the connection to be closed and reopened again; when the patch is not used, the receiver cannot handle the packets fast enough so there is less time to post new buffers and hence the mentioned RNR NACKs. So what happens is that the application *thinks* it posted a certain number of packets for transmission but these packets are flushed and do not really get transmitted. Since the connection gets opened and closed many times, each time netperf gets the CPU time that otherwise would have been given to IPoIB to actually transmit the packets. This can be verified when looking at the port counters -- the output of ifconfig and the oputput of netperf (this is for the case without the patch): tx packets ========== port counter: 1,543,996 ifconfig: 1,581,426 netperf: 5,142,034 rx packets ========== netperf 1,1304,089 Signed-off-by: Eli Cohen <eli@mellanox.co.il>

* IB/mlx4: Optimize QP stampingEli Cohen2008-07-15
| | | | | | | | | | | | | | | The idea is that for QPs with fixed size work requests (eg selective signaling QPs), before stamping the WQE, we read the value of the DS field, which gives the effective size of the descriptor as used in the previous post. Then we stamp only that area, since the rest of the descriptor is already stamped. When initializing the send queue buffer, make sure the DS field is initialized to the max descriptor size so that the subsequent stamping will be done on the entire descriptor area.

* IB/sa: Fail requests made while creating new SM AHMoni Shoua2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch solves a race that occurs after an event occurs that causes the SA query module to flush its SM address handle (AH). When SM AH becomes invalid and needs an update it is handled by the global workqueue. On the other hand this event is also handled in the IPoIB driver by queuing work in the ipoib_workqueue that does multicast joins. Although queuing is in the right order, it is done to 2 different workqueues and so there is no guarantee that the first to be queued is the first to be executed. This causes a problem because IPoIB may end up sending an request to the old SM, which will take a long time to time out (since the old SM is gone); this leads to a much longer than necessary interruption in multicast traffer. The patch sets the SA query module's SM AH to NULL when the event occurs, and until update_sm_ah() is done, any request that needs sm_ah fails with -EAGAIN return status. For consumers, the patch doesn't make things worse. Before the patch, MADs are sent to the wrong SM so the request gets lost. Consumers can be improved if they examine the return code and respond to EAGAIN properly but even without an improvement the situation is not getting worse.
